Rats are extremely common globally, living on every continent except Antarctica, and are deeply integrated into human settlements, thriving in urban environments due to readily available food, water, and shelter in homes, sewers, and buildings, with populations increasing in many cities. They are opportunistic pests attracted to even clean homes by simple food sources (crumbs, pet food) and entry points (small cracks, gaps), posing health risks by spreading diseases and damaging property through gnawing.
Rats are a common problem for many households across the country. In fact, the North West was one of the top three regions in the UK that exceeded the national ratio of rat call-outs per 1000 people! Rats will roam in your house or garden on the lookout for food, and they are not fussy as they will eat almost anything.
The bush rat or Australian bush rat (Rattus fuscipes) is a small Australian nocturnal animal. It is an omnivore and one of the most common indigenous species of rat on the continent, found in many heathland areas of Victoria and New South Wales.
Wild rats are not used to human contact and will bite when handled or when people attempt to feed them by hand. The nocturnal creatures have also been known to bite sleeping people, particularly children and infants, on exposed body parts such as fingers, hands, toes and the face when foraging for food.
Rats are attracted to houses primarily by easy access to food, water, and shelter, especially warm, cluttered, and dark spaces like attics, basements, and wall cavities, with common attractants including unsecured garbage, pet food, birdseed, fallen fruit, leaking pipes, and clutter like cardboard boxes or woodpiles that provide nesting sites. Sealing entry points, removing food/water sources, and reducing clutter are key prevention steps.
Scratching noises typically result from rodents moving through loose insulation, burrowing within drywall cavities, or navigating wooden framing members. These sounds often indicate nest construction or expansion activities in wall voids, attics, and ceiling spaces.
Rats are excellent climbers, so it's not out of the realm of possibility that they could get into your bed. However, it is unlikely. This is because rats are typically only active at night, and they are on a mission to find food and water sources.
Look for signs of rat or mouse infestation: Rodent droppings around food packages, in drawers or cupboards, and under the sink. Nesting material such as shredded paper, fabric, or dried plant matter. Signs of chewing on food packaging.
“Rats are most scared of predator scents, strong smells like peppermint or vinegar, sudden loud noises, and barriers they can't chew through. These triggers exploit their natural survival instincts and drive them away.”
If there are garbage cans and dumpsters around, they will use those too, as a means of cover from predators. Rats also crawl up trees during the day to look for food sources. In a city, rats tend to hide in sewers and other public places during the day where they can avoid predators.
Keep Your House Clean: Rats are attracted to food, so regularly clean up food scraps, store food in airtight containers, and maintain a tidy kitchen. Avoid leaving pet food out overnight. Trim Vegetation: Rats can climb trees and bushes to enter your home.
Rodents mistaken for rats
Unusual Odour: A strong, musky, or pungent ammonia-like smell caused by concentrated rat urine, which is more noticeable in severe or established infestations.
These rodents are scavengers and will invade any home in search of food and a safe place to raise young, and if your home isn't clean, it will satisfy both criteria and be at risk for infestation. Bird feeders and other types of food items that leave residue also attract rats and mice.
Many people keep their windows cracked to let in fresh air. If you do not have screens, rats can crawl right through that gap. However, they can also get in if your screen is torn or ill-fitting. Rats can also get through gaps around the windows, so make sure and seal them as well.
This is because rats and mice are nocturnal animals and tend to come out around 12am – 3am looking for food. If you do see rats or mice in the daytime then you have a much larger problem.

Rats may leave an area if they cannot find sufficient sustenance, but they might also adapt by scavenging. Proactive sanitation efforts can significantly deter rats and encourage them to seek food elsewhere.
What most people mistake for bites are the fact that rats will crawl all over you while you're sleeping. These researchers explain that a rat will not biting you, but it's sharp little claws and feelers that are on its feet will become irritating to you and give you the feeling that you have been bitten by a rat.
Rats cannot climb smooth, slippery surfaces like glass, polished metal, or slick tiles due to lack of grip. How do I stop rats from climbing my walls? To prevent rats from climbing your walls, install smooth metal wall guards, trim overhanging tree branches, and seal any gaps or holes in the walls.
Sleeping with the lights on will not effectively keep rats away.
Scream or squeal
Generally it is uttered by a rat who does not know what to do in that situation and is completely lost in its fear and sees no way out of the situation.
Mice and rats commonly seek refuge in the cozy spaces in walls of your home. This is the most common place you will hear their quick light tapping and scratching sounds. FYI - walls act as a hidden highway system for them to move unseen through out a home.
Rodents—such as mice and rats—absolutely can chew through both drywall and insulation. Their teeth are incredibly strong and keep growing, so they need to gnaw frequently to keep them from getting too long.
